Answer:
Explanation:
The impulse equation is
Δp = FΔt, where Δp = final momentum - initial momentum, F is the Force exerted on an object, and Δt is the change in time. In this equation,the entire right side defines the impulse. In other words, FΔt is the impulse; thus the change in momentum an object experiences is due to its change in impulse and is directly proportional to it.
Therefore, once we find the change in momentum, that is the impulse the object experiences. Δp = final momentum - initial momentum, where
p = mv and p is momentum.
so
and
so
; therefore,
Δp = 25.0 - 17.5 = 7.5 which is the unit for momentum
In order to develop this problem it is necessary to use the concepts related to the conservation of both potential cinematic as gravitational energy,
Where,
M = Mass of Earth
m = Mass of Object
v = Velocity
r = Radius
G = Gravitational universal constant
Our values are given as,
Replacing we have,
Therefore the speed of the object when striking the surface of earth is 4456 m/s
